Abstract

Novel speckle interferometric methods are described which offer a potential for whole field measurement of angular distributions on a curved surface. The technique encodes the angular distribution related phase by introducing topographic information in the interferometer in a controlled manner. The methods are simple to implement and provide broad range tunable sensitivity characteristics. Preliminary results obtained by applying digital speckle pattern interferometry are presented.
